Detailed explanation-1: -Chemical buffers in the body are substances that can absorb extra hydrogen ions preventing a change in pH.
Detailed explanation-2: -Base: A solution that has an excess of OH-ions. Another word for base is alkali.
Detailed explanation-3: -A solution having free/excess hydrogen ions is called an acid. A solution having free/excess hydroxide ions is called a base. So according to the above definition, clearly acids have more free hydrogen ions. pH of a solution gives the measure of the acidity or alkalinity of that solution on a logarithmic scale.
Detailed explanation-4: -A buffer is the combination of a weak acid or base and a salt of that weak acid or base. Buffers can be made from three combinations: (1) H 3PO 4 and H 2PO 4 −, (2) H 2PO 4 − and HPO 4 2−, and (3) HPO 4 2− and PO 4 3−.
